Employees who handle chemicals must be trained on the chemicals they are using per Globally Harmonized System of Classification and Labeling of Chemicals (GHS), and P&G Professional™ is here to help.


What is GHS?

OSHA revised its Hazard Communication Standard (HCS) to align with the United Nations’ Globally Harmonized System of Classification and Labeling of Chemicals (GHS). Employers must train employees on new label elements and standardized format for Safety Data Sheets (SDSs).

OSHA Resources

Occupational Safety and Health Administration (OSHA) was created to ensure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance.

In order to ensure chemical safety in the workplace, information about the identities and hazards of the chemicals must be available and understandable to workers. OSHA's Hazard Communication Standard (HCS) is now aligned with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS).
